    you say it heats to 180 and stops How ?

    does the stat switch off ?
    does the stat and motor switch off ?

    its a simple system so cant be a lot

    how are you measuring the temp and what have you got it set to ie 200 220 ?

    have you checked the knob is fully operating the stat i.e the actual temprature against the set temprature.

    Hi,
    I move the knob to 100 then 150 light goes off i turn it to about 180 it never gets that hot . I can see the element glowing red but beforeit gets to 180 the element goes off the fan motor keeps running and it starts to cool down the knobgoes onto a switch which turns the stat all operatingok.

    i assume the sensor is in the correct position and the correct stat is fitted 00489378

    if your using an oven temperature guage put is as close to the sensor as you can get it and see what you get

    It looks like it has 2 cooling fans – are either/both running (especially the one located between the 2 ovens)? If not it could be tripping the chassis overheat cut out on the back of the oven.

    went out for another look there is a small cut out thermostat above the fan motor which looks like a one shot thermostat which cuts out about 180 ,but somehow
    cuts back in I bypassed it to tryand it worked perfectly, new cut out ordered thanks for the help with this one,
